Cable length

The length of the cable that is equipped with a mouse with the possibility of a wired connection (see "Type of connection").

When choosing this parameter, you should first of all take into account the distance from the manipulator to the connection port: a cable that is too short may simply not reach the connector, and a cable that is too long may get tangled at hand and create inconvenience. As for specific values, the most modest wire length in modern mice is 1 m or less ; such devices are intended mainly for laptops. Most desktop manipulators come with cables that are 1.1-1.5m or 1.6-2m long, with some models running longer than 2m.

Sensor

The model of the sensor installed in the mouse. This information is indicated mainly for models equipped with high-end sensors, which are significantly superior in their capabilities to simpler solutions. Such characteristics are important primarily for gaming mice, so most of the devices for which the sensor model is specified belong to this category.

Knowing the name, you can find detailed data on the sensor and evaluate its capabilities. Note that one of the most popular brands nowadays, under which advanced sensors are produced, is PixArt ; on the market are often found, in particular, sensors PixArt 3212, PixArt 3325, PixArt 3327, PixArt 3335, PixArt 3360, PixArt 3389, PixArt 3395. The second common brand is Avago (recently owned by the same PixArt); the most popular model of this brand is Avago 3050, the simplest and most affordable representative of gaming sensors.

Sensor resolution

Resolution of the sensor responsible for tracking mouse movements on the work surface. Specified in DPI — dots per inch.

The physical meaning of DPI as a whole is as follows. The sensor of a modern mouse works on the same principle as the camera matrix, and consists of pixels. And DPI is the number of pixels that fall on 1 inch of the underlying surface (length or width), "visible" by the sensor.

It is believed that more DPI means a more advanced sensor and mouse in general; nowadays, models for 3500 – 5000 DPI, 12000 DPI, 16000 DPI even more are not uncommon. In a way, it is — high resolution contributes to accuracy. However, the only thing that is directly determined by this indicator is the speed at which the cursor moves across the screen: the higher the resolution of the sensor, the greater the number of pixels that the cursor will move when the mouse itself moves a certain distance. At the same time, it is worth recalling that too high a speed is even more undesirable than too low. So the real need for high DPI ( 1000 and above) arises mainly when working on large screens (4K resolution and more); for more modest displays (HD and Full HD), smaller values are often enough.

Max. acceleration

The greatest acceleration during movement, at which the mouse maintains normal performance; if this indicator is exceeded, the cursor may “break down” (moving to an unexpected place due to incorrect processing of data from the sensor).

The faster the mouse moves, the greater the acceleration acting on it. Accordingly, this parameter determines the sensitivity to sudden movements, the extent to which this model is able to normally perceive and process such movements. High values of maximum acceleration ( 40 G, 50 G) are important first of all in dynamic games, especially for professional e-sportsmen and advanced enthusiasts. If the mouse is bought for relatively simple tasks (working with documents, surfing the web, etc.), you can ignore this indicator.

Max. speed

The ips (inches per second) parameter is the linear speed of mouse movement, expressed in inches per second, at which the manipulator's sensor is able to read the surface. In top models, the maximum mouse movement speed often reaches 400-600 ips, but devices with ips in the region of 200 are more common.

Polling rate

The polling rate shows how often the mouse sensor communicates with the computer about cursor movement. The parameter is measured in hertz (Hz), and one second is taken as a unit of time when evaluating it. The smoothness and speed of cursor movement directly depends on the sensor polling frequency. Directly related to this is the mouse response time - this is the time period during which the signal about the movement of the manipulator will reach the display of a change in the cursor position on the screen. Response time is measured in milliseconds (ms). The more hertz the mouse has, the shorter the response time it demonstrates.

Number of buttons

The number of buttons provided in the design of the mouse. However, the term "buttons" can also refer to specific hardware solutions — for example, a solid touch area used in many Apple mice counts as two buttons, because. it is divided into two working areas. But the clickable wheels, as well as the power button, are not taken into account in this calculation.

The minimum number of buttons for modern mice and other similar manipulators is two : this is the number that is necessary for comfortable work in most modern operating systems. If there are more than two keys, this means that there are additional buttons responsible for specific actions. So, even relatively inexpensive devices can be equipped with 3 – 4 buttons ; in addition to the 2 main buttons, they can have, for example, 2 side thumb keys, or 1 double/triple click button (see below). Solutions for 5 – 6 buttons are extremely popular nowadays; among them are many gaming mice, where the mentioned thumb buttons are supplemented with a double / triple click, a sniper button and/or a DPI switch (see also below about these functions). And in the most multifunctional models, 7 – 8 buttons and even more can be installed. In some cases, this number exceeds a dozen and a half; such mice are usually gaming devices designed for RPGs and other simil...ar genres where it is important to have a wide range of actions at your fingertips.

Sniper button

The presence of a separate "sniper button" on the mouse.

This feature is found mainly in game models (see "By Direction"). When you press the sniper button, the mouse sensitivity (DPI) is significantly reduced (usually by half) and, accordingly, the movement of the cursor / sight slows down; to restore the original settings, just release the button. One of the most popular uses for this feature is sniping in shooter games. This is due to the fact that when using an optical sight with magnification (especially high), the standard mouse sensitivity may be too high for comfortable aiming, and it will be more convenient to reduce it.

Most often , the sniper button in the mouse is located on the side, under the thumb.

Switches

The brand of switches (switches) installed in the mouse. Also, these parts are often called "mikriki" — from the term "microswitches". Usually, the characteristics indicate the brand of switches used in the main buttons (left and right); additional buttons, usually, are equipped with other switches, often simpler and cheaper.

The mics are directly responsible for the operation of the keys when pressed. Accordingly, the quality of the mouse, as well as the feel and comfort of the user, depend on the quality of these parts: different switches can vary in stiffness, ease of operation and the sound of pressing. And the brand of switches is not specified for all mice, but only for models equipped with advanced elements. In other words, this parameter is indicated in cases where the brand of the microswitch is a sign of the high quality of the "rodent". Typical examples include mics under the brands Omron(considered premium) and Huano(Chinese counterparts of quite comparable quality). Light Strike and Razer switches are also pulled up to them.

We emphasize that in this case, not a specific model is indicated, but a general brand under which mikriks are released (sometimes also their type, opto-mechanical or mechanical). At the same time, the same brand may include different models of switche...s that differ in features: some are “quiet”, others with a normal sound, some with increased accuracy, others with an extended service life, etc. So the features of these parts should be clarified separately. However, the detailed characteristics of mikriks are important mainly for demanding users, in particular professional cybersportsmen.
